Question about 1990 Toyota 4Runner
My Toyota 4-Runner did the exact same thing and we found that the wire harness for the O-2 sensor fell onto the catalytic converter and melted causing it to groung out and blow the EFI fuse. Repaired the wires and no problems!

If you didn't mess with the wiring (cause some people do) you have a short to ground somewhere. basically you have to follow the power flow until you lose power and the short is going to be between the last spot you tested that had power (battery voltage) and the spot were you lost power. hope this helps
